A method of reinforcing a ceramic sandwich structure, the method comprising:
- forming a ceramic core, the ceramic core comprising a plurality of voids extending entirely through the ceramic core;
- assembling the sandwich structure by disposing the core between and in physical contact with a first panel and a second panel such that the plurality of voids extend from the first panel to the second panel;
- and
- weaving a plurality of z-fibers at least partially through a thickness of the sandwich structure;
- wherein at least one of the plurality of z-fibers physically contacts each of the first panel and the second panel, extending entirely through the thickness of the sandwich structure and at least one of the plurality of voids.
